anti-inflammatory, antimitotic, antineoplasic, antibacterial, and antimycoticagent. In this work we studied for the first time the antiviral activity of usnic acid and its derivatives against the pandemic influenza virus A(H1N1)pdm09. A total of 26 compounds representing (+) and (−) isomers of usnic acid and their derivates were tested for cytotoxicity and anti-viral activity in MDCK cells by microtetrazolium

to be the most effective. Our study revealed that (−)-usnic acid exhibited higher antiviral activity than its (+)-enantiomer, but in the pairs of enantiomer derivatives such as enamines, pyrazoles and chalcones, the (+)-enantiomers were more potent inhibitors of the virus. For other groups of compounds the inhibiting activities of the enantiomers were comparable. Further optimization of the structure
